What Are the Most Common Causes of Lymph Node and Neck Pain?
Lymph node and neck pain can be caused by a variety of ailments, from the benign, such as the common cold, to the more severe, such as HIV and AIDS. Most people will experience lymph node and neck pain at some point in their life and, usually, the cause of the pain and swelling will resolve itself. For people experiencing lymph node and neck pain that persists, it is recommended to seek out the advice of a primary care physician. Lymph nodes, which are part of the lymphatic system, act as a filtering system for the human body. Technically a cluster of reticular connective tissue, lymph nodes are filled with lymphocytes that trap bacteria and viruses as they circulate in the body. This is one of the main causes of lymph node and neck pain. As the lymphocytes multiply as a result of a bacterial or viral infection, swelling and tenderness can occur.
